Historic England lists buildings in three grades: Grade I for buildings of exceptional interest (about 2.5% of all listed buildings), Grade II* for particularly important buildings of more than special interest (about 5.8%), and Grade II for buildings of special interest (about 91.7%). Listing protects the whole building, inside and out.

Every entry on the National Heritage List for England whose point lies inside the ONS 2022 built-up-area boundary. One list entry can cover a terrace or a group of buildings. Neighbourhood dots: the population-weighted centre of each Census 2021 output area, coloured by its neighbourhood’s (LSOA’s) share of homes built before 1919 (Valuation Office Agency, March 2025).

Historic England’s conservation areas layer, supplied by councils (incomplete in places, so a page fact, never graded). Hectares are the part of each area inside the built-up area.

The first 4 entries were listed in 1950. 6 came in 1985, in the national resurvey of the 1970s and 80s. Only 2 have been added in the last 15 years.

Two measures, each ranked against every UK town of 1,000 or more, with protected heritage counting twice as much as the age of homes. Protected heritage counts each listed building by its grade (Grade I three points, II* two, II one), each scheduled monument and battlefield two, and each registered park or garden by its grade; it is ranked both per 10,000 residents and as a total, so a village with one fine church doesn’t outrank a historic city. The second measure is the share of homes built before 1919, from the Valuation Office Agency’s council tax records. History is a character grade: it describes the town and isn’t part of the overall grade.

The official list counts 12 listed buildings in Seaham, including Police Station. A conservation area has protected part of it since 1997. George Holley (1885), Tom Wilson (1896) and John Bainbridge (1880) are among the 18 people born here before 1900. Otherwise the figures are ordinary: like most towns its size, it has no Grade I building; per resident it sits near the middle of UK towns; and 16% of its homes were built before 1919, close to the 15% in the typical UK town.
